Use wget in install script if curl is not available?

• [ x] Confirmed this is a problem with running a brew command and not brew installing or the post-install behaviour of one or more formulae? If it's a formulae-specific problem please file this issue at the relevant tap e.g. for Linuxbrew/homebrew-core https://github.com/Linuxbrew/homebrew-core/issues/new
• [ ]x Ran brew update and retried your prior step?

• [ x] Ran brew config and brew doctor and included their output with your issue?

To help us debug your issue please explain:

• What you were trying to do (and why) I am trying to create a bootstrap script to install preferred command line working environment in a distro agnostic way to be able to use my tools of choice and configuration on different remote servers I may or may not have install access on.
• What happened (include command output) bash: curl: not found
• What you expected to happen Pull files with wget if possible
• Step-by-step reproduction instructions (by running brew commands)

  temp="${TMPDIR:=/tmp}"
  wget https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh -O \
  "${temp}/brew-install.sh"
  sh "${temp}/brew-install.sh"

Features

It seems wget is more universally available than curl (or at least a minimal debian installation does not seem to have curl). Would it possible to use wget in install script to fetch content from the net during installation? Maybe try curl if wget is not available ?

I am not sure if this would be beneficial to 90% of the user base, but I think it would be nice to be able to install LinuxBrew on as many different Linux installations as possible with no other depedency.

On servers with no install permissions I would probably have to install curl from source or fetch appropriate binaries, it is kind of against the point of creating this script.

Or maybe there is another way to make it possible ?

The Debian Docker image debian:latest hash neither curl nor wget installed, interestingly enough.

I agree that it would be a useful feature to bootstrap Linuxbrew on a system without curl using wget. It's not a priority item for me, but I'll add it to my wish list. In the mean time, here's a workaround for you.

cd ~/.cache/Homebrew/
wget https://linuxbrew.bintray.com/bottles/curl-7.58.0.x86_64_linux.bottle.tar.gz
wget https://linuxbrew.bintray.com/bottles/openssl-1.0.2n_1.x86_64_linux.bottle.tar.gz
wget https://linuxbrew.bintray.com/bottles/zlib-1.2.11.x86_64_linux.bottle.tar.gz
brew install curl

I've added a wiki page here: https://github.com/Linuxbrew/brew/wiki/Bootstrap-with-wget

Thanks, didn't know I could download bottles. Still discovering LinuxBrew, great work bringing Brew to Linux 👍

Hi @sjackman , Do you mind elaborating on the workarounds you gave? I still ran into problems... cd ~/.cache/Homebrew/ wget https://linuxbrew.bintray.com/bottles/curl-7.58.0.x86_64_linux.bottle.tar.gz wget https://linuxbrew.bintray.com/bottles/openssl-1.0.2n_1.x86_64_linux.bottle.tar.gz wget https://linuxbrew.bintray.com/bottles/zlib-1.2.11.x86_64_linux.bottle.tar.gz brew install curl

The work around has unfortunately gotten a bit trickier, since the path to the file in ~/.cache now includes a hash of the url. It's still possible, but unfortunately not easily described here.

Here's the location of the portable-ruby bottle.

Here's the location of the other bottles and their paths on disk including the hash:

I'm afraid I won't be able to give you exact instructions as I'm short for time.
